Hereinafter, the above-mentioned water-soluble skin protectant and oily skin protectant&apos; will be described in detail. (A) Water-soluble skin protectant The above-mentioned water-soluble skin protectant preferably has water solubility or water dispersibility and inhibits the occurrence of rash or inflammation, and can suppress the plaque when rash or inflammation has occurred. The rash or inflammation progresses, or the person with the rash or inflammation is alleviated. Specific examples of the water-soluble skin protectant include: (1) various plantings

O:\9I\9I025.DOC -13- 1320706 extract, (2) collagen, (3) natural moisturizing ingredient (NMF), 13-butanediol, propylene glycol, dipropylene glycol, glycerin, etc. (4) an arginine, an anthracene derivative (for example, an organic acid salt of 2-(2-hydroxyethoxy)ethyl hydrazine (for example, succinate, glycolate, lactate, malate, citric acid) Salt, tartrate, etc.), etc., keratin softener, (5) Guaiazulene 'tannin, gallic acid derivatives and other anti-inflammatory agents. As a water-soluble skin protectant, a plant extract or a natural moisturizing component (NMF) is preferably used in view of solubility in water, skin protection effect, and cost. Specific examples of the plant extract include oat extract, seaweed extract, grapefruit extract, witch hazel extract, mantle extract, arborvitae extract, aloe extract, Cork extract, squid extract, feverfew extract, eucalyptus extract, peach leaf extract, etc. In particular, 很高' can achieve high skin protection by using grapefruit extract, witch hazel extract, arborvitae extract, scent extract, cork extract, eucalyptus extract or peach leaf extract. When a highly water-absorptive polymer is used as the material of the absorber, it is preferred that the water-soluble skin protectant described above does not cause deterioration of the absorption property of the water-absorbent polymer, etc., so that it is preferable to use grapefruit. Extract, witch hazel extract, Luo Hanbai extract 'Aloe vera extract, Cork extract or peach leaf extract as a water-soluble skin protectant, especially good for grapefruit extract, witch hazel extract or Luo Hanbai extract Things. The plant extract can be obtained by, for example, drying one or more parts of the whole plant or leaves, bark, roots and branches of the various plants O: \91\9I025.DOC -14· 1320706 仃'When it is pulverized without drying, it is extracted by solvent under m or heating, or extracted by a suction device such as a sputum extractor. When using 1&gt;3 • butanediol extract as a plant extract, not only the solubility in water is continuously increased, but also the explosion-proof measures are not required when the fiber or the absorbent article is subjected to heat treatment. x, a thin layer or fiber applied to the surface layer or composed of the material may also inhibit the absorption properties of the absorbent body constituting the absorbent article from being lowered. In general, the plant extract contains, in addition to the active ingredient, the solvent component and the water used in the extraction. The amount of the active ingredient of the plant extract in this state (the amount after removing the volatile solvent component or the water) may be approximately 0.001 to 5% by weight. In the case of using H-butanediol as a solvent component for extraction, the sum of the active ingredient of the plant extract and I,% butanediol may be in the above range. The amount of the active ingredient of the plant extract relative to the amount of the solvent component is preferably about 1 to 1% by weight. The water-soluble skin protectant described above is preferably fixed to a specific position of the diaper absorbent article by the state in which the moisture is detachable (in the diaper 7 of the figure, the waist cuffs 30a, 30b, the girdle 35a) 35b, each of the regions 45a, 45b, and each of the three-dimensional guards 60a, 60b), particularly preferably by contact with urine, feces, menstrual blood, vaginal secretions, etc. (hereinafter, collectively referred to as "excretion") Or, by contact with sweat, is fixed to the absorbent article in a state in which the excrement or sweat dissolves or disperses. When the water-soluble skin protectant is present in the absorbent article, it can be preserved in the absorbent article when it is worn. The vine J easily reaches the wearer's skin, so its skin protection effect is easy to appear.

For example, a thin layer of a water-soluble skin protectant cured is impregnated into the thin layer, and 10 times of water (liquid temperature 25 C) t' water skin protectant can be fully dissolved or dispersed. It can be called "fixed by the state in which the moisture can be detached". The water-soluble skin protectant can be transferred from the absorbent article to the wearer's skin by means of moisture, and may be transferred to the wearer's skin by an auxiliary means other than moisture. Fixing the water-soluble skin protectant to the absorbent article, for example, by applying a coating liquid containing a water-soluble skin protecting agent to a thin layer or an inner thin layer or a thin layer specific position of the material of the thin layer. By making it work. In the present invention, it is particularly preferable that the above-mentioned coating liquid contains a surfactant in the waist portion (four). Therefore, the water-soluble skin protecting agent is stably fixed to the inner surface of the thin layer before or during the period of draining, thereby inhibiting the water-soluble skin protective agent from being transferred to the skin of the wearer shortly after wearing, and water-soluble. Skin protectant - lifts to the skin side. Further, by using the surfactant in combination, it is also advantageous in terms of the reproducibility of the absorbent body of the hydrophilic or absorbent article, or the anti-recording property, the cloth workability, and the like of the non-woven fabric or the absorbent article manufacturing apparatus. When excretion occurs, most of the water-soluble skin protectant and the surfactant-transfer to the absorber side are transferred, but at this time, one part of the water-soluble skin protectant is transferred to the skin side of the wearer. So even if the excrement comes into contact with the skin, water

O:\9I\91025 DOC 1320706 Soluble skin protectant also protects the skin and inhibits or alleviates the production of spot treatment. The transfer of water-soluble skin protectant to the skin is easy to cause by sweating or excretion, so it is borrowed. The moisture in the absorbent article is increased by the absorption of the excrement, and even if the state is over a long period of time, the skin protection effect of the water-soluble skin protectant can be sufficiently continued. As a result, # the skin protection effect protects the wearer's skin and suppresses or alleviates the plaque treatment. When the water-soluble skin protectant is fixed to the absorbent article, when the object to be fixed of the water-soluble skin protectant is a woven fabric, the fiber constituting the nonwoven fabric may be preliminarily fixed with the water-soluble skin protectant, and The fiber is only made of non-woven fabric for the material. In this case, the water-soluble skin protectant is fixed, for example, by containing a water-soluble skin protectant and a fiber treatment agent containing a surfactant or a higher alcohol, if necessary, and immersing the coating liquid. Coating, spraying, rolling, etc., can be attached to the fiber after the fiber is dried and β is fixed by any method, and the 纟-soluble skin protectant can be fixed to the object. The surface may be continuously attached in a film form or a layer form, or may be attached discontinuously (for example, in the form of particles or discontinuous film). The preferred amount of the water-soluble skin protectant is 'fixed depending on the type of the water-soluble skin protectant to be used', and can be appropriately selected within the range which does not adversely affect the skin. When the amount of the water-soluble skin protectant is too large, the skin protection effect is saturated, so the upper limit of the amount of the amount of the meal is determined in consideration of the skin protection effect and economy.植物Use a plant extract as a water-soluble skin protectant to apply the water-soluble skin protectant to the fiber surface

ΟΛ9 丨汐丨025.DOC -17- 1320706 When fixing, it is preferable to set the fixed amount to 〇 〇 〜 5 重量 /, particularly preferably 〇〇 5 to 2% by weight. The water-soluble skin protectant is detachable by moisture in the region formed by the hydrophobic ray fiber in the manner of the inner side of the waistbands 3〇a and 3〇b shown in Fig. 1(A). Preferably, it is (4) a water-soluble skin protectant and a surfactant, and it is more preferred to use i, 3_T diol in combination.丨, 3 Butanediol can be used as a water-soluble skin protectant in a manner described above, but particularly preferably when a plant extract is used as a water-soluble skin protectant, as a method for fixing the plant extract to a fiber Use as a solvent on the surface. Any of an anionic surfactant, a cationic surfactant, and a nonionic surfactant can be used as the surfactant contained in the coating liquid described above. Specific examples of the surfactant include polyoxyethylene sulfonate sulfonium k S strontium metal salt, alkyl sulfonate metal salt, polyoxyethylene alkyl phosphate metal salt, and alkyl phosphate metal salt. The fatty acid diethylamine, the sorbitan fatty acid ester (any of the mono-, di-, and tri-esters), the alkyl glucoside, the polyglycerin fatty acid ester, the alkyl succinate metal salt, and the like. As the above respective metal salts, for example, a sodium salt or a potassium salt can be used. The surfactants may be used alone or in combination of two or more. In view of the repetitive absorbability of the hydrophilic or diaper absorbent body, or the rust preventive property or the non-woven fabric processability of the non-woven fabric or diaper manufacturing equipment, it is particularly preferable to use the following among the surfactants. 1 or more kinds: polyoxyethylene alkylate metal salt, alkyl wall acid ester metal salt, fatty acid diethanolamine, sorbitan fatty acid ester, alkyl glucoside, and alkyl benzoate Metal salt. O:\9I\9102S.OOC -18- 1320706 Also, considering the viewpoint of stably fixing the water-soluble skin protecting agent to the surface of the hydrophobic f-fiber, it is preferable to use a hydrophilic surfactant and a hydrophobic mixture. Sexual surfactant. For example, when two or more kinds of nonionic surfactants are used in combination, HLB (hydrophilic-lipophilic balance) can be used as an index. A hydrophilic surfactant having an HLB of 8 or more, particularly 1 Å or more, and a hydrophobic surfactant of 6 or less, particularly 5 or less, substantially a hydrophilic f-surfactant/hydrophobic surfactant = 9 〇 /1 〇~wt%) When mixed, the thin layer made of hydrophobic fiber as the main material is stabilized and the water-soluble skin protectant is fixed, and even after the absorbent article is worn, The wearer's skin is in contact with the oily skin protectant, but the water-soluble skin protectant tends to remain on the thin layer. Further, at the time of excretion, the water-soluble skin protecting agent is easily detached from the surface of the thin layer. In addition to the surfactant or the fiber treating agent, the above coating liquid may be added with an antistatic agent, an antioxidant, a pH adjusting agent, a smoothing agent, an emulsifier, an antibacterial agent, an antifungal agent, a perfume, and the like. (Β) Oily skin protectant It is particularly limited to contain the skin of the wearer. For example, cosmetics can be used as an oily skin protectant to protect and heal the equivalent energy, and there is no user in the field as a softener. Specific examples of the oily skin protectant include liquid stone soil, organic eucalyptus oil, animal and vegetable oils (eucalyptus oil, eucalyptus oil, safflower oil, keratin, and cod liver oil), glycerin monooleic acid, and glycerin Sour vinegar, triglyceride, aliphatic bond (tetradecyl-U3-dimethylbutyl hydrazine, standard 仏 dimethyl dimethyl hydrazine: Wl\9i 〇 2s D〇c • 19- octane Base-1,3-dimethylbutyl ether, palmitoyl i, 3-methylpropyl

When it is small, it is easy to uniformly coat the oily skin protectant on the thin layer, and it can be stably fixed to the thin layer regardless of the temperature change, so that the oily skin protectant can infiltrate and diffuse the absorbent body without hindering. In addition, it is easy to visualize the so-called two-stage skin protection effect as follows: initially the oily skin protectant is transferred to the wearer's skin, and then the water-soluble skin protection The oily skin protectant is applied to the absorbent article or its material. For example, the oily skin protectant is placed in a tank of a coating device (applicator), and if necessary, heating is performed to improve fluidity. It is applied to a diaper or a specific position of the material. Examples of the application method of the oily skin protectant include a disk coating method, a slit spray method, a curtain mist method, and a sleek method. Flow method, spiral spray method, gravure method, bead method, etc. When the method of spraying by air is applied, the oily skin protectant is sprayed on the object to be coated in the form of fine particles or mist. Therefore, the 'oily skin protectant is 'macroscopically continuously distributed on the coated article, but is microscopically discontinuously distributed on the surface of the coated article. As a result, it is easy to obtain a skin protection effect in a wide range of performances, and it is possible to ensure the liquid permeability of the surface layer and to effectively utilize the absorption property of the absorber. The problem is that the oily skin protectant is applied by air misting, and the desired absorbent article is resigned. Of course, even if it is applied through the air: spray:

The inserts 35a, 35, and the entire inner side of the leg cuffs 45a, 45b (the side in contact with the wearer's skin) or a part thereof. The above-mentioned diamine derivative is transferred to the wearer's skin with the wear of the diaper, and the following action can be made to enable the oily skin protectant to function: (1) inhibiting the excrement from directly contacting the wearer's skin and suppressing Skin irritation caused by excrement, (2) weakening the friction between the skin and the diaper to reduce skin irritation caused by the diaper, and (3) improving the moisture retention capacity and barrier function of the stratum corneum after absorption through the skin. Thereby, skin rash caused by the diaper 7 can be suppressed. _ Considering the idea that the diamine derivative is effectively transferred to the wearer's skin as the above-described diamine derivative, it is preferably used: 36. The 〇 viscosity is approximately 5,000 mPa.s or less, especially 2 〇〇 to 5 〇〇〇 claws, especially 500 to 2000 mPa.s, or the viscosity adjustment is performed in this manner. By using the above-mentioned city, the oily skin can be transferred to the wearer's skin in a cost-effective manner. When the viscosity is 5GGG mPa.s or less, the transfer property to the skin is extremely excellent, and it is not necessary to use a large amount of oily skin protectant to exhibit the desired skin rash suppressing effect. Moreover, the influence on the absorption is small. In addition, when the viscosity is 2 〇〇 heart 3, the storage period before wearing is longer than the case of 'absorbent article 0.\9J\9|〇25 OOC -26-1320706, it can effectively prevent the above two 醯The transfer of the amine derivative to other sites' is thus effective in obtaining the desired skin protection effect. Further, the "viscosity of the diamine derivative" in the present invention is measured by the same method as the method for measuring the viscosity of the oily skin protectant according to the first embodiment described above. The diamine derivative used in the present invention is preferably one in which the viscosity of Wenlu is small. Specifically, it is preferred that the viscosity at 36 ° C is within the above range, and the viscosity at 80 C is 50 to 200 mPa·s. When the temperature dependence of the viscosity is small, it is easy to uniformly coat the diamine derivative with a thin layer, and it can be stably fixed on the thin layer regardless of the temperature change, thereby infiltrating the absorber by the diamine derivative. 'Diffusion without hindering absorption. The application of the diamine derivative to the absorbent article or the material can be carried out in the same manner as the application of the oily skin protectant of the first embodiment described above. The coating amount (coating amount) of the diamine derivative is preferably selected in consideration of not only the influence on the absorption energy of the absorbent but also the texture and skin protective effect. For example, when the diamine derivative is continuously applied in a film form or a layer form, since the contact area with the wearer's skin is enlarged, the amount of transfer of the bisamine derivative to the skin is increased and it is easy to cover the skin extensively. The skin protection effect is raised, but on the other hand, the absorption performance of the absorbent body is easily lowered, and the sticky feeling is caused. The coating amount of the dimethylamine derivative (refers to the coating amount of the diamine derivative in the actually applied range) is preferably about 0.05 to 2 〇g/m2 in consideration of skin protection effect, texture, and the like. Within the range 'better than 〇1~1〇g/m2. Especially when applied to a thin layer on the surface, it is preferably 01~5 g/m2 0\9I\9I025 OOC •27·

The amount of money applied can be determined by the difference in weight between the object to be coated and the object to be coated after the application of the diamine derivative. Depending on the necessity, it is also possible to use two kinds of coating methods in the absorbent article of the i type. For example, it is also possible to apply a P-position application tray coating method to the buttocks in order to obtain a high skin protection effect, and to use a spray type in the vicinity of the urination site in order to achieve both absorption performance and skin protection effect. When the diamine derivative is also applied to the absorber, the water absorption speed of the surface layer (JISL 096 water absorption, water absorption speed, and error can be made by setting the coating amount to the above-mentioned range. The dropping method)) is controlled to be less than (7) seconds. Therefore, it is possible to obtain an absorbent article having practical absorption properties. The diamine derivative to be used may be a single species or a plurality of plural species. If necessary, it can also be combined with other oily skin protectants. As the other oily skin protectant, there is no particular limitation on the protection of the wearer's skin and the healing ability, for example, makeup can be used. In the field of the mouth, it is used as a softener. As the other oily skin protectant described above, an oily skin protectant as shown in a specific example of the first embodiment can be used. The absorbent article of the above embodiment is an unfolded diaper, but the absorbent article of the present invention may also be a pants-type diaper.
